At least 40 bodies — all of them wearing uniforms identifying them as army officers — have been found in a mass grave inside the headquarters of the Bangladesh Rifles paramilitary in the capital, Dhaka, authorities said Friday. The discovery brings to at least 62 the number of army officers who have been found dead after mutinous paramilitary forces took dozens of superiors hostages at the Bangladesh Rifles (BDR) headquarters on Wednesday. The Rifles laid down their arms after Prime Minister Sheikh Hasina agreed to grant them amnesty.
